Referring specifically to the dfawingswherin like reference characters designate lik'e o'n mila-r parts; an airdrome 'is suggested at lfliriI'igure 1. This 'airdrome'has' 'a roof I i and' m'ay have'side walls i2. 'Such walls ll and 152 are adaptedf'to be constructed-of r eix'iforoed concrete and trubbl'e and, for instance, from twenty to fifty fe'et thickness. It will be realized that the were 1 2 oi themselves areinsiifficient to euppert the roof 55 to another; taken on {the time elevation routing tewa'r d 45 other" preferred manner.

In order torespectively-supportthe rate'wi'ght of" the roar -H I provide a riiiilti plieity crimividualir-oc fsuppor-ts at 13. Ea'dlrof these 'sl-ipports l3 is bapahle df individual-complete retraction beneath 'the fieor level "mend the" supports are so close together that they have to 'be retraoted in order to permit "aircraft *su'ch as it 'to enter or leave the' airdrome or more" beneath the roof 11. To avoid weakening orunduly weakening the support of the roof ll, only dne 'ertwo or a very limited number or the supports 1 3 are retracted at 'a timeto ehablefiimited firoveme'nt of the aircraft 11"5 whereuponaiteri'tiie aircraft passes the retracted supports the same are again extended before another support 'or alirrlited number of them are retraeted'to permit further slig htza'dvance oftheaircrait. a

My invention isnot limited to :any particul'ar construction of the supports rl'3 as thesaime may be operated niechanicallypl'iydraulicallyor.inany However; I"show:an operativeembo'diment by way 'of'anfeizample.

Such supportis detailed in Figures 3 t0'7.

As previously tated and as well shownwin Figure '7 the-supports are capable of retraction completely beneath the ground line "H withwtlieir upper surfaces'flush therewith.

Each support '13 has a basal stationary-barrel below the floor "I 4. Disposed across barrel l fiabove'itsbase is a partition 11 c'entrallyci which is'fastened' a lrub- IE8 by means of screws at it. Above partition -l1,-:a ce'ntral telescopic barrel -or cylinder istprovided' while any desired number-of telescopicharrels-or'foylinbetweenthe same-and the barrel lB,"barr'els-2-B and2l being c'apabieof retraction completely within the'barrel it "below the floor line '14 as shown in Figure '1 and also capable of extensioninto support'ng engagement with-thereon ashestslmwn in'Figurel. Said barrels or cylinders -23 and Zlareinteriorly in communication-with each otherand the interior of the barrellfi in order tobeprejected or extended through the admissioninto the same of hydraulic fluid through 'a-zpipe or'hose 22*attached to partition I 1 and-in coinmunication with:api)"rit 23in the latter; The hydraulic fluid Y'fromi any suitable source "passes" through i a Conduit 2 1 through a valve mechanism -25' and thenee rito the -pipe fl. Said valve mehariism E5 is en- 'nected through a link 6 with a roe-leer -21 pivi'ted at 28 to a block or support 29. Rocker fifl also has a 30 pivoted thereto which controls-andutlet valve mechanism 3| communicating with the source of hydraulic fluid supply and with the interior of the barrel I through a conduit 32 connected to partition ii and registering with an opening or port in the wall thereof. Thus the rocking of the element 27 controls the supply and exhaust of hydraulic fluid to the barrel I5, in order to extend or retract the sections 2|] and 2|, it being clear that the weight of such sections is sufficient to retract them when the valve mechanism 3| is open;

It will be clear that any suitable means may be provided to effect a seal between the valves or cylinders I5 and 2| the adjacent cylinders. tachment and detachment of the barrels and 2| from each other and from the barrel I6, said bushings 33 are preferably removably fastened in place by bolt or screw means as at 34 to rings 34a welded or otherwise secured to the tops of the i cylinders. I

At the base of each barrel or cylinder 29 and 2| a ring 35 is fastened, such rings increasing progressively in diameter in downward direction as shown in. Figure 3. retracted position of the supports, rests on the hub |B- while the intermediate ring rests on the lowermost ring and the uppermost ring rests on the intermediate ring.

The cylinders or barrels i6 and 2| are held against turning relatively to each other by the interfitting of guide ribs 35 extending longitudinally on'the barrels l5 and, withnotches 37 providedin flanges 38 of the rings 35.

Each ring 35 has radial bearing 4!] in which a'hub 4| is journaled. A vertical shaft 42 passes through the hub H3 and hubs 4|, being journaled in the hub Hi and stuffing box thereof. Hollow or tubular shafts 44 extend rigidly one from each hub 4| and shafts are concentric with the shaft 42 and each is rela- Figure 5 the rings as suggested in or retracted as shown in the other figures.

Keeper members 52 are fastened to the inner surfaces of the cylinders or barrels l6 and 2| and flanges 38 are adapted to engage the adjacent ones at their limit ofprojection. Such keepers 52 heads 4-8 extend when projected. Thus each cylinder or barrel I6, 20 and 2| in addition to the hydraulic pressure or in the absence thereof will support each other through the medium of the latch heads 48 and keepers 52 and-the The shaft 42 may be operated in any suitable The lowermost ring in the l spokes 39 and a, central 9 and are accurately fitted to In order to enable at-' a body to be manner. For instance, a short shaft 54 is journaled on the exterior of the stationary or basal barrel I6 in a bearing 55 and a bracket 56 and also in the element 29. Keyed to the shaft 54 is an operating hand wheel 57. 7 element 29 is a locking device 58 which is engageable in recesses in the rocker 21 and wheel 51, one at a time, to lock one against movement while the other is free for operation and vice versa. On shaft54 a bevel gear wheel meshes with a bevel gear wheel 60 carried by a vertical shaft 6| journaled in a bearing 62 by which the valve structures 25 and 3| are mounted.

At the base of shaft 6|, a bevel gear Wheel 63 is keyed and which meshes with a bevel gear wheel 64 carried by a shaft 65 journaled in a U-shaped bearing structure 66 fastened at the bottom of barrel l5. Gear wheel 61 keyed to shaft 65 meshes with a bevel gear wheel 68 keyed to the aforesaid shaft 42. As a result, through the turning of the wheel 51, the intermediate gearing described and traced will rotate the shaft 42 and shafts 44 as a unit and simultaneously operate the heads 48 to move theminto or out of the keepers 52.

It will thus be seen that a multiplicity of the supports l3 are employed, that they are arranged relatively close together and that each is individually operable to retract the same flush with or below the ground level M or to project same into supporting engagement with the roof II. It will also be realized, that but one or a. limited number of the supports 3 should be retracted at the same a time to permit a limited movement of the aircraft |5 whereupon as soon as the aircraft |5 moves over a retracted support, such support should be I extended. Thus at ing or leaving the neath the roof I Various changes they fall within the tion. I
